The Health Information and Quality Authority (HIQA) has reported that Mass screening programmes using non-contact devices (for example, infrared thermal scanners) were not found to be effective in identifying infectious individuals and limiting spread of disease. It has also stated that it is unclear whether long-term immunity to SARS-CoV-2 is possible. The studies show an antibody was detected in nearly all individuals up to 3 months after infection and over 90% of patients had developed a neutralizing antibody response.
